- VDSL (FTTC)
- VDSL (FTTC) as an Ethernet router plugged in to a VDSL modem (no longer a common setup, as Openreach no longer provide VDSL modems)
- VDSL (FTTC) or ADSL as a bridging modem to a third-party PPPoE router (e.g. FireBrick).
- FTTP using the Ethernet WAN port doing PPPoE.
Factory Default Admin Username/Password
Note: An AAISP configured router will have a different username and password.
The B10B has an autogenerated supervisor password (hashed from the serial number). Earlier models left a md5crypt type hash in /etc/passwd, however firmware AAVF.10 introduced these being stored in /etc/shadow. You may have some success reading this file by logging into the router as the "admin" user via SSH. You will need to crack the hash (eg with hashcat), the password will be 8 characters long using characters 0-9,a-f (lower case)
